Title: High pressure sodium lamp for dc lighting
Inventor: OGATA YOSHIRO
IPC: H01J61/36
Filed: 1985-06-11
Abstract: PURPOSE:To prevent ununiformity of luminous brightness by constructing the cathode side closing member of the two closing members of a luminous tube with cermet. CONSTITUTION:The high pressure sodium lamp of high color output for DC lighting is an alumina luminous tube, and its diameter is narrowed down at both end parts, and the electrode conductor 2 consisting of niobium tube is sealed in the inside surface of one end part of the tube by glass cement and the cermet 5 is sealed in the inside surface of the other end part of the tube by glass cement. the cermet 5 holds the cathode 6 on itself and plays a role of conductor, and works as a heater, though only slightly, during the discharge current is flowing in the cerment 5. Therefore, the temperature of the end part of the cathode side of the luminous tube 1 is kept adequately, hence the point of lowest temperature of the luminous tube 1 is created in the end part of the anode side of the tube, so the cataphoretic phenomenon associated with DC lighting is not induced in the inside space of the luminous tube 1, and almost constant discharge condition is realized independently to the lighting directions. By this, the almost constant lighting characteristic without ununiformity of luminous brightness can be obtained.

Title: Timer circuit
Inventor: YAMAUCHI SATOMI
IPC: H03K5/13
Filed: 1985-06-11
Abstract: PURPOSE:To attain low cost for the entire device by constituting a time limit setting section of a timer circuit with one output part, a delay circuit and an input port. CONSTITUTION:When a computer control section 1 sends a H level control signal to the output port 2, the port 2 sends an output signal to a delay circuit 4 and an output terminal 5. The circuit 4 sends a delayed output signal to an input port 3 after a set delay time. The port 3 sends a detection signal representing the fetch of the delayed output signal to the control section 1. As a result, the control section 1 brings the control signal sent to the port 2 to an L level. Thus, the timer signal is sent from the terminal 5 by a delay time of the circuit 4.

Title: Rotary drum
Inventor: YANAGIHARA HISAFUMI
IPC: G11B5/02
Filed: 1988-05-24
Abstract: PURPOSE:To transmit a signal in a wide band signal by arranging electrodes in upper and lower drums separating the electrodes with air flow due to revolution and executing the giving and receiving of the signal by holding a prescribed distance. CONSTITUTION:An electrode 5 is arranged in an upper drum 1 in a revolving side and an electrode 9 is provided in a lower drum 2 in a fixed side. When a revolving drum is stopped, the electrodes 5 and 9 are contacted. However, when the upper drum 1 is revolved, the electrodes are slightly separated by the air flow. Then, the giving and receiving of the signal is executed between a revolving head 4 and a prescribed signal processing circuit through a capacitor which is formed in such a way. Since the gap of this capacitor is exactly set to be extremely small by the air flow, a transmission band can be widely set and it is not necessary to strictly execute gap control. Then, the manufacture of the revolving drum goes to be easy.

Title: Compression capacity reducing method and apparatus for solid waste
Inventor: KATADA KATSUO
IPC: G21F9/00
Filed: 1987-05-25
Abstract: PURPOSE:To obtain a compressed product with stable dimensions, by compressing material to be compressed longitudinally with a parallel die surface while the side thereof bound is released after the side thereof is pressed toward the center thereof at several points. CONSTITUTION:A housing container Z holding material X to be compressed is retained as erected in a forming mold 3. Then, with the lowering of the mold 3 on an inclined surface, the side of the container Z is deformed horizontally inward at several points by a wedging effect in contact with a diameter reduction mold 36. As the diameter reduction of the container Z reaches its maximum limit, the side of the material X being compressed is formed into a projection and a tooth of a recessed groove 41. Here, with the lifting of the forming mold 3, an intermediate molding G is obtained with the side of the material X being compressed formed into a tooth. The molding G is combined with a tapered part of an upper cylindrical die 37 fitted into the groove 41 between protruding parts to reduce the lateral diameter until the whole of the material X being compressed slips out down the projection. Moreover, as a vertical compression develops, an internal pressure of the molding G rises and causes a deformation in the shape of a cylindrical forming chamber M to obtain a compressed product Y.

Title: Fluorescent lamp
Inventor: SHIMIZU TAKAO
IPC: H01J61/35
Filed: 1986-06-04
Abstract: PURPOSE:To simplify a process, reduce the dispersion of quality and obtain a lamp having a good distribution of luminance, by providing a reflection layer having an aperture, on the outside surface of the lamp. CONSTITUTION:After a protective film 2 and a phosphor film 4 having an aperture 5 are formed on the inside surface of a glass bulb 1, a reflection film 6 is formed on the outside surface of the glass bulb so that the reflection film has an aperture 5. The reflection film 6 is made of a silver-colored exposy paint by printing. Light emitted from a phosphor is reflected by the reflection film 6 on the outside surface of the lamp and goes out through the aperture 5. Since the reflection film 6 is located on the outside surface of the glass bulb 1, the light emitted from the phosphor 4 passes through glass twice by the time when the light returns to the inside surface of the glass bulb after being reflected by the reflection film, the light is attenuated in the glass. However, if the light transmitting and absorbing properties of the reflection film 6 are low and the reflectance thereof is high, the output of the light from the aperture 5 is high as a whole.

Abstract: PURPOSE:To obtain a loud-speaker telephone set for automobile superior in service quality by erasing a passing-round signal only in a certain partial band of the voice signal band for the purpose of preventing the signal, which a speaker in the automobile sends, from passing round to the speaker after a certain time. CONSTITUTION:A transmission signal Sk from a microphone 3 is inputted to a low-pass filter 14, and only its low band component SLk is taken out and is inputted to an echo canceller 15. An estimated value -rLk of a low band component rLk from a band separating filter 16 is estimated in the canceller 15, and its phase inverted signal is inputted to an adder 17. Consequently, the signal rLk is erased in the output of the adder 17. Its erase error eLk is inputted to a band synthesizing filter 18. A high band component rHk from the filter 16 and the erase error eLk are synthesized into an original voice band signal RDk by the filter 18. This signal is inputted to a speaker 2 and an echo canceller 1. Consequently, the low band component is erased from a passing-round signal rk of the signal inputted from the microphone 3 with respect to the signal RDk.

Title: Flow meter
Inventor: YOSHIKURA HIROSHI
IPC: G01F1/32
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a flow meter by which it can be judged accurately whether or not an ultrasonic sensor senses any failure. SOLUTION: In case where the judgment is NO in the step S2 ((amplitude B)<(reference value E of amplitude)) and it is YES in the step S4 (B>=E), it is supposed that any air bubble passes through a transmission path where a second transmission element is transmitted, and its result is given no processing in the step S6 (information on failure of a second ultrasonic sensor) and the step S7. Thus, the detection accuracy of failure can be improved.  On the other hand, in case where the judgment is NO in the step S4 (B<E) and a first elapsed time T1 is longer than a reference time G (judgment is YES in the step S5), the judgment of NO in the step S4 (B<E) means not passage of air bubble but failure of the second ultrasonic sensor 42), and an alarming device gives an information (step S6), and then a driving signal instead of reception signal of a reception element is selected (step S7) and the phase of driving signal and reception signal is compared with each other so as to calculate a flow rate successively.
